    禁止中国开放权重模型对美国弊大于利

    作者主张,禁止中国开放权重模型会切断美国 AI 生态的低成本创新来源,却难以阻止已公开权重的全球传播。文章认为,廉价模型有助于降低应用层推理成本、支持企业自主托管数据并促进价格竞争,而既往技术限制也未必实现预期目标。

    In the Internet era, the more your software or application got used, the cheaper it got to run per user. The R&D cost was fixed, and each new user added a sliver of bandwidth, storage, and support. As your application grew, your fixed costs spread across more people, and cost per user fell. AI is different because inference is a real variable cost. It looks more like manufacturing business. Every query burns tokens, and you pay for those tokens whether you rent the model through an API or host

    GPU 管理分析:为何闲置 GPU 如同停飞的飞机

    大规模智能体集群会让实时推理、批处理、再训练和评测争用有限的 GPU,使调度与利用率成为核心问题。GPU 隔离和沙箱可支持安全共置,但仍需根据显存占用、延迟容忍度、运行时长和优先级分配任务;僵化分区反而可能造成容量闲置。

    Benedict Evans 谈 token 定价的思考方式

    Benedict Evans 分析 token 定价的供需与成本结构,认为当前供给紧张是暂时的,所有变量都在变化,市场将在未来几年重新平衡。他指出推理毛利率约 40-50%,但训练成本远高于收入,且需求主要来自软件开发这一单一用例。他通过移动数据和半导体制造的类比,提出基础模型可能走向低利润的商品化基础设施,除非出现网络效应、监管干预或其他未预见的变化。
